性強化に寄与し得る。As described above, when the synthetic resin foam 8 is attached to the outer peripheral surfaces of the long axis and short axis hanger beams 2 and 3 of the steering hanger member 1, an external force is applied to the long axis and short axis hanger beams 2 and 3. When applied, the synthetic resin foam 8 also generates stress, cooperates with the long axis and short axis hanger beams 2 and 3 to resist the above-mentioned external force, and contributes to strengthening of the long axis and short axis hanger beams 2 and 3. obtain.

確認している。According to tests, the outer diameter is 60 mm and the wall thickness is 1.
When a PP (polypropylene) foam having an expansion ratio of 5 and a wall thickness of 5 mm was applied to a 6 mm steel pipe, it was confirmed that the rigidity could be increased by 10% compared to a steel pipe not having such an adhesion. doing.

ることになる。In particular, since the synthetic resin foam 8 can obtain a large wall thickness as compared with a non-foamed synthetic resin having the same weight and the same weight, this can be obtained by using the long axis and short axis hanger beams 2, 3.
When applied to the outer peripheral surface of the synthetic resin foam 8, the synthetic resin foam 8 can be given a large outer diameter to obtain a large section modulus, and the rigidity of the long axis and short axis hanger beams 2, 3 can be effectively enhanced. Will be.

The weight increase due to the adhesion of the synthetic resin foam 8 is small compared to the case where the outer diameter and the wall thickness of the steel pipe constituting the above are increased.
